B&M 3713 RESTORATION
WORK PROCEEDS
The Boston & Maine 3713 Restoration project has continued since June,
1999, with major
portions of the work continuing as you read this newsletter. Work began
with the disassembly
and cataloging of the parts by the shop workers at the Steamtown National
Site. Once this was
completed, the L&WV Chapter hired a contractor, at a cost of $25,000,
to remove the asbestos
from the locomotive.
During 1999 our contractor
completed approximately 1273 hours of work, with an additional 586
hours approved for continuation of the boiler restoration. The work is
made possible by
continued donations that have been received from people who have responded
to our fund raising
drive, and by visitors to the Steam town site who have contributed money
in the various donation
boxes.
The locomotive is currently being restored at the shops of the Steam town
National Historic Site
in Scranton, Pennsylvania. When you visit Steam town, find out about the
free shop tour, and see
for yourself what has been done. If you have made a donation to the fund
drive, see what your
contribution has helped make possible.
